Improvement in stove-drums

J OHN GILSON, OF PORT IVASHINGTON, VISOONSIN.

IMPROVEMENT IN STOVE-DRUMS.

Spccilication forming part of Letters Patent No. 210,933, dated December 17', 1878; application filed October 4, 1878.

To all whom it may concern:

Be it known that I, JOHN GILSON, of Port Vashington, in the county of Ozaukee and State oi' Wvisconsin, have invented certain new and useful Improvements in Stove-Drums; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in thelart to whichit appertains to make and use the same, reference being had to the accompanying drawing, and to letters of reference marked thereon, which form a part of this specification.

The accompanying drawing represent-s a sectional side view of my invention.

The object of my invention is to furnish im` proveniente in stove-drums, to be used either upon a stove or in connection with the stovepipe, at a distance therefrom, for retardiug the current of heated air in its passage from the stove to the chimney, and for procuring a more perfect radiation otl heat, all of which is further explained by reference to the accompanying drawings, in which- A represents the periphery of the drum, which is constructed of sheet-iron in an ellipti cal shape. B represents the heads of the drum, which are constructed of cast-iron, each having openings opposite' each other for the reception of the cylinders C, D, E, and F, which cylinders respectively extend from one head to the other, thus connect-in g the heads together. The cylinders thus serve to retard the current of heated air, and their inner surfaces provide a large extent of radiating-surface.

G' is the inlet-pipe, which either rests upon the stove or is connected therewith by the pipe. H is the outlet-pipe. I are sheetAmetal partitions, which connect the cylinders respectively with the periphery of the drum, and serve to further retard the heated current. J and K are dampers, by which the draft is regulated. When they are open, in ,the position shown, there is nearly a direct draft from the lower to the upper side of the drum, but when closed the air follows the course indicated by the arrows, and is consequently lunch ion ger retained in the drum, and the amount of heat radiated is thereby greatly increased.

The rods L, to which the dampers are attached, extend through the heads of the drum, and are provided with handles, by which the dempers are opened and closed.

M are bolts of the ordinary construction. They extend from one head of the drinn to the other, and connect the two together, and hold them firmly against the sides of the drum.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

r)She combination ot the drum A, the heads B, cylinders O, D, E, and F, partitions I, and dampers J and K, all substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

JOHN GILSON.
